Question

How does Conductivity vary with Temperature?

Answer 1

Conductivity varies with temperature-

The vibration of metal ions increases with temperature increase, this results in an increase in resistance of metal and hence, a decrease in conductivity. In the case of electrolytic conductors, the ion is the charge carrier and with the increase in temperature, ionization increases, and hence, conductivity increases.

For example, if we talk about wire, when temperature increases, the resistance value of wire also increases therefore conductivity of wire will decrease.

Because resistance is inversely proportional to conductivity.
